Abstract
A selective growth mask having a plurality of openings is formed on a semiconductor substrate. Desired epitaxially grown regions are formed on the openings by controlling the upward epitaxial growth from the openings. Two resonance tunnel barrier diodes are formed on respective separated two epitaxially grown regions and connected together. Thereafter, a tunnel barrier diode is formed on the connected two resonance tunnel barrier diodes to form a composite element having an SRAM function. A number of composite functional elements can be integrally formed on a semiconductor substrate by selective growth and a small number of fine processes.
